The housing has a well surrounding the curved U-portions of the tubes of the matrix in spaced relation a shell is diposed between the wall and the curved U-portions of the tubes of the matrix. A flexible seal is mounted between the wall and the shell for preventing flow of hot gases therebetween, and at least one brush seal is mounted between the shell and the curved U-portions of the tubes of the matrix for blocking passage of hot gases therebetween. The brush seal comprises a plurality of bristles clamped at one end in a recess in the shell and fanning out towards the other free end to tangentially and sealingly contact the outermost row of the tubes of the matrix.
